DOUBLE-ROW CULTIVATOR.

Application filed December 30, 1908.

To all whom it may concern:

Be it known that I,- DoN E. LONG, of

Peabody, county of Marion, and Stateof Kansas, have invented a new and useful Improvement in Doul'ile-R-ow Cultivators, of which the following is a specification.

My inwution relates to improvements in double row cultivators and is applicable more particularly to those forms of double row cultivators in which a rectangular frame is sustained at its rear end b an axle carried by ground wheels, the said frame being provided with projecting tongues for the attachmentof the draft animals and the forward end of the rectangular frame carrying a suspended draft bar to which the gang barsare attached and in which the plows are'elevated and depressed by suitable levers pivoted above the axle and attached by links to the plow beam. In these cultivators the arrangement of parts is such that not only the weight of the frame and tongue. but also the weight of the plow beams and their parts, are largely sustained by the neck yoke, and act as a dead weight upon the necks of the horses. In addition to this weight, the strain exerted by the force requil od to draw the plows through the gros'ud acts to depress the forward part of the frame work and adds great pressure in a downward direction upon the neck yoke. These plows are usually provided with some form of steering gear by which the ground wheels are turned by the driver or operator independently of the movement of the team. This turning moverm=ut results in a pressure in a sidewi'sefglirection upon-the tongues and a consequent; side strain upon the neck yoke and upon the'animals.

invention is designed to remove the; 1 difiiculties and maintain the frame of the machine and the attached beams on a lewl, and consists broadly in 'providing the for ward end of. the frame-work of the cultivator with a pivoted truck arranged in advance of the hitch-mechanism, and in pro viding said truck with means whereby the forward end of the frame (and the, beams carried thereby) may be raised and lowered in relation to the ground in ordergto; e tg il m'on vatorsaid frame-work in a horizontaland also to equalize the several cix ti shovels sustained by said beams relatively for the same depth of cultivation for all conditions of the ground.

The invention consists further in provid- Specification of Letters Patent.

Patented Mar. 16, 1915.

Serial No. 469,962.

ing means for hitching the draft-animals to the main frame of the machine at a point to the rear of the truck whereby the draftanimals are placed in close proximity to the forward central end portion of the main frame, and by which arrangement the steering of the truck, due to movement of the attached tongue, may be accom lished independently of the draft or pul of the animals. a

The invention consists further in providing the truck (upon which the independently steered frame is supported at its front end) with two wheels arranged relatively close together, and, also, in supporting upon said truck, means for raising and lowering the frame at its forward end in relation to the ground whereby'the cultivator-shovels are positioned.

Referring to the drawings Figure 1 is a plan view of a cultivator with my improvement embodied therein. Fig. 2 is a front elevation of the same. Fig. 3 is a sectional side elevation. Figs. 4, 5 and 6 are details on an enlarged scale of the draft mechanism and attached elevating and depressing means.

In the accompanying drawings, wherein similar letters of reference are used to indicate corresponding parts in each of the several views :1 indicates the frame-work of the cultivator, provided at its rear end on each side with pivoted stub axles 2, upon which are mounted ground Wheels 3. These axles are capable of rotation through the oporation of the steering mechanism 4. Big idly attached to each of the stub-axles 2 is a short link 4*, and pivotally connecting with each of these links is a transverse bar l". When this bar is actuated by the driver, by hand or foot, it will be positioned at an angle to its normal position, and whereby the links 4" are moved to turn the Wheels in one or the other direction, as the driver may desire to position them. The forward end of the frame 1 carries an arch. bar 5 to which is attached a series of dragbars supporting plows 6 forming the. gangs by'means of which two rows may be cultivated. Pro

'icqt ll q wgardly from medians; '1 in a pogives greater strength to the structure.

The U-shaped framevis braced by cross bars 11 and 12 and is provided with a pivot 13, to which is attached an evener 14, provided at its rear side with links 15 connected to a central chain 16 passing over pulley 17 carried by 'a cross-piece 18 attached to the U-shaped frame 8. This link and chain form a truss to take the strain upon the evener and thus enable me to use lighter material in the construction of said evener.

The underside of the U-shaped frame is provided at each side with loops '-or eyes 19, through which the evener is passed and sustained against displacement.

The forward end of the U-shaped frame is rigidly secured to a hollow casting -20, within which is mounted a plunger 21, preferably tubular in form and attached at its lower end to a fifth wheel 22. The plunger 21 is slotted as shown at 20* and a pin is passed through the slot in such manner as to prevent rotation of the plunger and to act as a stop for the upper end of a spring 20 which rests at its lower end on the top of the fifth wheel 22, previously referred to and which aids in controlling the operation of the actuating lever (hereinafter referred to) by facilitating the raising of the plunger and, thus, of the frame, and by cushioning the frame when it is depressed. The plunger, spring, etc., are preferably housed within the casting 20, as shown.

The upper end of the plunger is provided with a casting 23 having attached thereto a sector or rack 24, having pivoted thereto a lever 25 with the usual handle and pawl arrangement 26 adapted to engage with the rack. The forward end of the lever 25 is extended as shown at 27 and connected by a pivoted link through the slot 20 in the upper end of the plunger 21. The arrangement of parts is such that movement of' the lever 23 will raise and lower the U.-shaped frame and the forward end of the frame of the cultivator in relation to the fifth wheel of the machine and the truck to which the fifth wheel is. attached.

The lower casting22 of the fifth wheel has attached thereto a short axle 28, upon which is mounted a pair of supporting to the pin which extends wheels 29 adapted to straddle the center of the space between the two cultivated rows. These wheels should be and are preferably such distance apart as to straddle the ridge left by lister cultivation of corn, or the intermediate ridge left by plowing. A tongue 30 is pivoted to the axle 28 between the said supporting wheels 29 and extends forward for attachment to the neck. yoke. The doubletrccs and swingletrees are atpreviously i tached to either end of the evener referred to, and it will be noted in connection with this that the only weight sus tained by the necks of the horses is that of the forwardly extending tongue 30.

As will be observed by reference to the drawings, the truck supporting wheels 29 are centrally located at the forward end of the frame and serve both as a support to the forward end of the frame and as a point upon which leverage may be exert-ed to retain the frame and suspended plow beams in a level and effective position at all times. The truck supportingwheels 29 also serve to take all side strain due to steering action on the rear ground wheel and relieve the necks of the horses from this burden.

As will be apparent from the drawings, the draft animals in my machine are hitched to the machine in rear of the forward truck arrangement andtherefore the draft is on the main frame of the machine and not on the truck, as usual in this class of machines.

The operation of the mechanism described is obvious.

While I have shown a draft attachment and my improvement applied to a double row cultivator of a usual type, it is apparent that similar application could be made to other implements of a like nature and that such application of this improvement would be within the scope of my invention. I
